DOER Research: Acoustic Camera Particle Image Velocimetry (PIV)

This project investigates the use of a 3D acoustic camera to acquire two-dimensional velocity vector fields from PIV analysis. An experiment was performed to quantify the two-dimensional velocity field of a simple laboratory flow using PIV with both 3D acoustic camera images and standard optical camera images, along with ADV transect measurements, to determine whether the acoustic camera PIV results are accurate. The success of this project will lead to an entirely new technique to measure flow velocities in turbid environments in the field, one that yields substantially more information than the technologies currently available (i.e., two-dimensional velocity vector fields) and allows velocity gradient based hydrodynamic signals to be directly estimated.
